What if the Black Plague had killed off almost all Europeans? Then the Reconquista never happens. Spain and Portugal don't kickstart Europe's colonization of other continents. And this is what Africa might have looked like.
"Louise Fresco argues that a smart approach to large-scale, industrial farming and food production will feed our planet's incoming population of nine billion. Only foods like (the scorned) supermarket white bread, she says, will nourish on a global scale."
"In this exclusive, unedited interview, 'I Am Malala' author Malala Yousafzai remembers the Taliban's rise to power in her Pakistani hometown and discusses her efforts to campaign for equal access to education for girls. Malala Yousafzai also offers suggestions for people looking to help out overseas and stresses the importance of education."
A new analysis of sea levels and flood risk around the world offers more evidence that the brunt of climate change will not be borne equally.
More than a quarter of Vietnam’s residents live in areas likely to be subject to regular floods by the end of the century. Globally, eight of the 10 large countries most at risk are in Asia. These figures are the result of a new analysis of sea levels and flood risk around the world, conducted by Climate Central and based on more detailed sea-level data than has previously been available. The analysis offers more evidence that the countries emitting the most carbon aren’t necessarily the ones that will bear the brunt of climate change.
"Have you heard of Alexander von Humboldt? Not likely. The geologist turned geographer and South American explorer was a bit of an 18th century super scientist, traveling over 24,000 miles to understand the relationship between nature and habitat. George Mehler details Humboldt’s major accomplishments and why we should care about them today. See this TED ED lesson plan that accompanies the video."
"While people often say that borders aren’t visible from space, the line between Kazakhstan and China could not be more clear in this satellite image. Acquired by the Landsat 8 satellite on September 9, 2013, the image shows northwestern China around the city of Qoqek and far eastern Kazakhstan near Lake Balqash.
The border between the two countries is defined by land-use policies. In China, land use is intense. Only 11.62 percent of China’s land is arable. Pressed by a need to produce food for 1.3 billion people, China farms just about any land that can be sustained for agriculture. Fields are dark green in contrast to the surrounding arid landscape, a sign that the agriculture is irrigated. As of 2006, about 65 percent of China’s fresh water was used for agriculture, irrigating 629,000 square kilometers (243,000 square miles) of farmland, an area slightly smaller than the state of Texas.
The story is quite different in Kazakhstan. Here, large industrial-sized farms dominate, an artifact of Soviet-era agriculture. While agriculture is an important sector in the Kazakh economy, eastern Kazakhstan is a minor growing area. Only 0.03 percent of Kazakhstan’s land is devoted to permanent agriculture, with 20,660 square kilometers being irrigated. The land along the Chinese border is minimally used, though rectangular shapes show that farming does occur in the region. Much of the agriculture in this region is rain-fed, so the fields are tan much like the surrounding natural landscape."

"Weak and failing states pose a challenge to the international community. In today’s world, with its highly globalized economy, information systems and interlaced security, pressures on one fragile state can have serious repercussions not only for that state and its people, but also for its neighbors and other states halfway across the globe. The Fragile States Index (FSI), produced by The Fund for Peace, is a critical tool in highlighting not only the normal pressures that all states experience, but also in identifying when those pressures are pushing a state towards the brink of failure."
"Americans' understanding of who counts as 'white' has changed dramatically throughout the country's history and even over the last century alone. This map — which covers a decade of immigration to the US, from 1892 to 1903 — is a dramatic illustration of what it looked like when 'white' wasn't the same thing as European. Mouse over any part of the map to magnify it."
"By 2050, the world's population will likely increase 35 percent. But is growing more food the only option—or even the best? National Geographic investigates the challenges and solutions to feeding everyone on our planet, based on an eight-month series in National Geographic magazine. Visit http://natgeofood.com for ongoing coverage of food issues as we investigate the Future of Food today on World Food Day."

"It's perfectly human to grapple with questions, like 'Where do we come from?' and 'How do I live a life of meaning?' These existential questions are central to the five major world religions -- and that's not all that connects these faiths. John Bellaimey explains the intertwined histories and cultures of Hinduism, Judaism, Buddhism, Christianity and Islam."
"The Pew survey sorts people into major groupings--Christians; other religions, including Jewish and Muslim; and 'unaffiliated,' which includes atheist, agnostic and 'nothing in particular.' Roll your cursor over the map to see how faiths and traditions break down by state."
"Why are all the gas stations, cafes and restaurants in one crowded spot? As two competitive cousins vie for ice-cream-selling domination on one small beach, discover how game theory and the Nash Equilibrium inform these retail hotspots."
Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.
A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.
In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.
The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.
"For 75 years, Finland's expectant mothers have been given a box by the state. It's like a starter kit of clothes, sheets and toys that can even be used as a bed. And some say it helped Finland achieve one of the world's lowest infant mortality rates."
